Smartphone App Helps Snakebite Victims
Scientists in Denmark have developed a venom test kit to help doctors treat victims of snake bites. The kit was created to be simple and has only two pieces of equipment: a centrifuge and a smartphone.
For victims, surviving the snakebite requires the use of a treatment, known as anti-venom. However, receiving the correct form of treatment can be difficult. The victim must first know which kind of snake bit them. That is because each poisonous snake produces a different kind of venom.
The venom testing kit can help solve this problem.
Snake venom is made up of various protein patterns.
The different protein patterns in the venom can be used to determine the snake species. Catherine Larsen is a scientist at the Technical University of Denmark, or DTU. She said researchers found these patterns after testing different snake venoms with different small proteins.
Ivan Doudka is also with DTU. He explained that the kit works by using a smartphone app to analyze a plasma serum sample from the patient.
To create the sample, the patient's red blood cells need to first be separated. This is done by using a centrifuge which is a device created to separate fluids. The centrifuge is operated by hand and needs to be spun quickly to separate the substances.
The sample is then put into a special container that keeps the condition of the plasma serum the same. After 30 minutes, the sample is placed into a clear container called a cuvette.
The cuvette is used with a machine known as a spectrophotometer which analyzes the liquid by measuring the amount of light that is absorbed by it.
By connecting the spectrophotometer to a smartphone a smartphone app is used to show the results.
The app then identifies the type of snake and suggests the most effective anti-venom.
Andreas Laustsen, another DTU scientist, said the test kit will help doctors make quicker, possibly life-saving decisions.
The team's work could help the estimated five million people who are bitten by snakes each year. Those bites kill at least 100,000 people, and lead to around 400,000 venom-related amputations.

丹麦科学家开发出一种毒液检测套件，帮助医生治疗被蛇咬伤的患者 。该工具套件设计简便，只有两件设备：一台离心机和一部智能手机 。
对患者来说，被蛇咬伤后需使用抗毒血清才能存活 。然而，接受正确的治疗可能很困难 。患者必须先知道被哪种蛇咬伤，因为每种毒蛇都会分泌不同类型的毒液 。
毒液中不同的蛋白质形式能够确定蛇的种类 。凯瑟琳·拉森（Catherine Larsen）是丹麦科技大学（DTU）的科学家 。她说，研究人员用不同的少量蛋白质测试不同的蛇毒后发现了这些蛋白质形式 。
伊万·杜德卡（Ivan Doudka）任职于丹麦科技大学 。他解释说，该套件利用智能手机应用来分析患者的血浆血清样本 。
想要生成这种样本，首先需要分离出患者的红细胞 。这一过程是通过分离液体的离心机实现的 。而离心机是手动操作的，需要快速旋转才能分离出物质 。
之后将血液样本放入特殊容器内，保持血浆血清的状态不变 。30分钟后，再将血液样本放入名为“比色皿”的透明容器内 。
丹麦科技大学另一位科学家安德里亚斯·劳斯藤（Andreas Laustsen）表示，这一检测套件可以帮助医生更快速地做出攸关生死的治疗决定 。
